The Revo Calibrate Sunglasses give you unsurpassed clarity and a sleek look thanks to ultra light and durable materials. These shades are made with Serilium lenses which will block the glare from water, snow and the road and will be able to tolerate high velocity impact to such objects like gravel. They also feature an anti-reflective coating which keeps fingerprints, sweat and any other debris from getting your lenses dirty. The motion fit technology allows you to comfortably wear the Revo Calibrate shades without it affecting any of the pressure points.
